What you need to do is have talk to him and let him know what you think.
You also need him to answer you with the questions you have, be honest and forward about what you think. If he avoids the subject then it's time for you to make a real decision about the future with this person. If you are living with him move back to your folks house, if possible.
You don't give much else in your post so I don't know your age or anything else about you
